i just got my a8n-sli and 2x512mb ddr400 corsair xms ram. I tried starting up my computer and heard this loud beeping sound. I'm assuming it's because I'm using slot DIMM_A2 and DIMM_B2 compared to using DIMM_A1 and DIMM_B1 which it says to use in the manual. is it ok to stick with the current ram slots?
